Not for me
The only thing that it lets me carve is what’s already in the sd card. I wanted to eliminate the computer connection with this controller board, still using the computer with it. Do your research. The controller moves the steppers motors just fine.

Stops working after a few months
This is my second one to stop working after a few months. They just stop reading the card

3018 off line controller. I can't get it to read my G code.
The controller works to move the spindle manually. It runs the 3 sample G codes, but will not run my G code
